This is a tough choice. It may be perfectly legal to share it, but the fact that you're asking for other peoples "approval" to
share it, suggests that you have misgivings about sharing it. If you didn't, you would have already posted it. Follow your
conscience. If it tells you not to, then don't do it. I have been through the same situation. The only difference was I
purchased it from the person. It was for the pick 3, but I tweaked it to use for the pick 4 and had better results. I thought
about contacting the person to get his permission to share it for the pick 4, because I felt it was his system. But I didn't, and
I ultimately decided to keep it to myself. It's your decision, so do what you feel is right.
